Notes on Using the Battery Pack
Before using the battery pack, read the following precautions for correct use.
About the battery pack
The supplied battery pack is designed specifically for your VAIO computer.
For your safety, only use the supplied battery pack or an optional battery pack that is
specified by Sony.
For safety reasons, battery charging may be suspended at higher or lower temperatures.
While your VAIO computer is connected to an AC outlet with the AC adapter, it runs on
AC power, even if the battery pack is installed.
The supplied battery pack is not fully charged at the time of delivery.
While the battery pack is in use or being charged, heat builds up in the battery pack.
This is normal and is not cause for concern.
Do not use your VAIO computer without installing the battery pack as it may cause the
computer to malfunction.
About battery discharge
After battery charge, the battery pack will gradually discharge over time even while not in
use. If it is left unused for an extended period of time, the battery power may be depleted. It
is recommended that you recharge the battery pack before use.
About battery life
Battery life varies depending on usage and settings.
About battery deterioration and replacement
The battery pack is consumable. The capacity gradually declines through repeated
cycles of recharging and discharging. As a result, the battery life becomes short even if it
is fully charged and eventually the battery pack reaches the end of its life. If the battery
life has become short, check the battery status and replace the battery pack with a new
one specified by Sony.
If the battery pack quickly runs out of power after being fully charged or it has reached
the end of its life, replace it with a new one.
When using the power saving mode
If the battery pack runs out during Sleep mode, all unsaved data before your VAIO computer
enters Sleep mode will be lost and cannot be restored. Be sure to save all data before
placing the computer into Sleep mode.
In Hibernate mode, all data and status (such as window position, size, etc.) are saved to the
built-in storage device, so no data will be lost even if the battery pack runs out. If you cannot
connect the computer to an AC power source for an extended period of time, place the
computer into Hibernate mode.
